The numbers were written on the work order by the tech when he was at the house. He kept telling his dispatch that the signal was really high.

Hopefully an end to my problems: I called Comcast on Thursday morning because the pixelation was so bad on Thursday morning that most channels just showed a black screen. So I called from work and the rep wanted me to be at home to "troubleshoot". When I got home Thursday, the picture was perfect on all channels and the signal strength on the TiVo was back to the 80s and 90s and it's been that way ever since. I don't know what they did, but it worked and I'm hoping it stays working!

That's excellent news and encouraging for others experiencing similar issues.

We had problems with Comcast earlier this year as well. Three truck rolls and each tech (all different) said everything was "perfect"...often connecting one of there own DVR's and saying "See? The picture's great. Must be your TiVo." We knew it wasn't and on the fourth truck roll the tech left for about 20 minutes to work on the "head end"(?) and when he came back everything was indeed perfect. He said someone had made some "changes there" and that he fixed it.

Thanks again for posting your story...it's good to know that things can be resolved one way or another.

So the signal strength on the TiVo should be in the 80s-90s?

Mine is aroun 40-50 and I'm getting pixelation on a couple of HD channels and snow on many of the non-HD channels.

The SNR is usually in the 32-35 range and the RS Corrected on most channels remains at 0, while RS Uncorrected sometimes goes up a few points every once in awhile -- which is NOTHING like I had a week ago, where the RS Uncorrected would get into the MILLIONS within a few minutes; just rolling numbers!

When I first got the Series 3, I clearly remember playing around with all the menus and finding the signal strength meter and finding that all channels were at or near 100, so I think the higher the number on the TiVo, the better picture. When the signals were dipping below 55 or 60, that's when the pixelating started like crazy. 60-65 seemed to be the minimum on most channels for a clear picture.

Everything is still stable and even survived last night's snow storm; which frankly, I thought would bring all of the horror back, but this morning, everything was great.

What's also great is that no one from Comcast ever suggested that it was the TiVo causing the problems -- it is their CableCARDS in there, after all, and they do now refer to the "TiVo Series 3" by name on billing and in conversations I've had with customer reps.

YMMV, but IMO, if you've had a consistently good picture and no audio dropouts before, the problem is not with the TiVo, it's with the signal getting to the TiVo, so call the cable company and BITCH because at the prices everyone pays for TV, that picture should really be flawless 99.99% of the time!

I'm having some pixelation on my S3s, which I don't think is the standard problem, and I'm quite puzzled but it.

It only happens on one channel, SCI-FI (SD cable, digital), that I know of, it may happen on other subchannels on the same QAM carrier, but I don't know which channels those are. That's carried on a very low frequency RF carrier, 105MHz, it would be in the FM radio band usually, but its not the lowest frequency carrier.

When its happening there's a dropout every second or 2, constantly. The audio gets really quite annoying. With the 9.2 software at least the video doesn't break up totally, just show small patches of macroblocking.

This happened on one of my S3s, then later on it was on both of them. Then I swapped around some of the cables on my splitter (and really didn't do anything apart from unhook them, then hook them back up to different ports), and now its only happening on one of the S3s again. When it was happening on both of the S3s, I was thinking it was a source problem, but now as the same source is feeding both and only one is doing it, I'm not sure.

The signal strength is 95 on that channel. It would be 100 if I didn't have the distribution splitter (6 way) in there. As I said every other channel I've looked at is fine, with strengths in the 95-100 range. The SNR is 35-36, even when the problem is happening. When the problem happens the RS uncorrected just counts, fast. When its not happening I get zero for RS corrected and uncorrected.

I live in the North Dallas area and I have Verizon Fios cable, internet and telephone. I have been experiencing major pixilation for the last month or so - especially in the lower numbers.

We’ve had technicians try to help, installing new cards and a lot of different settings, with no improvement. Recently we have also starting having telephone interference - so we brought the tech back out to take a look.

To fix this problem he installed an RF Suppressor out at the box and low and behold the pixilation went away - completely. This is a better picture then I have ever had, absolutely no pixilation at all. No promise that this will help you, but the quality is so much better we actually call Verizon to let them know about this wonderful side effect.

Congrats on the newly found nirvana!

I know it's a stretch to ask, but is there any way you can post a photo of your new RF Suppressor, or possibly give us the brand, any model number you might find, etc.?

I've posted earlier about my pixelation issues, which are now mostly gone. But the remaining problem is just damn bizarre.

I am now seeing consistant pixelation issues on just one channel (ABC affiliate HD) on just two nights a week (Wed,Thursday)!

So Desperate Housewives records fine, no digital glitches at all, on Sunday. But shows like Private Practice, Dirty Sexy Money, and Grey's Anatomy all have digital hits every 3-5 minutes. So since DH is my wife's favorite show, while my TiVo doesn't think I'm gay, it does fear her more than it fears me.

The only real difference between Sunday and Wed/Thurs is that on Sunday, the Tivo is usually just recording shows (when doing DH, it's also recording another HD show), whereas on Wed/Thus it is usually recording 2 HD shows and we are also watching something. I am wondering if this is the issue, with a possible side-order of 720p->1080i upconversion being done in the TiVo as well (we have our TiVo do the format conversion).

Meanwhile, after about 3-4 weeks of continuous operation, RS Uncorrected on both tuners is 0, RS with Correcteds of 24 and 181, and SNRs of 34 or 35.

I occasionally see a hit on other channels but the rates are very low.

One weird idea that just occurred to me when I was previewing the posting was that maybe the hits are being caused when we FF through commercials on the program being recorded.

Meanwhile, after about 3-4 weeks of continuous operation, RS Uncorrected on both tuners is 0, RS with Correcteds of 24 and 181, and SNRs of 34 or 35.

The error statistics (Corrected and Uncorrected) only apply to the time since the last tune, ie since the TiVo started watching that channel. Its not telling you that you had zero uncorrected in the last 3 weeks, but only since the last time it changed channel on that tuner. There's a note on the diagnostic screen about time since last tune.

If you looked on Wed or Thursday while it was recording, it may show more errors.

This happened on one of my S3s, then later on it was on both of them. Then I swapped around some of the cables on my splitter (and really didn't do anything apart from unhook them, then hook them back up to different ports), and now its only happening on one of the S3s again.

I swapped the port the second S3 was attached to, and replaced the connector with a better one. I'm now trouble free on both S3s.

I don't know if its the swapping ports, or the changing of the plug which did it. I had a lot of trouble with crimp video connectors, they don't seem to like me, so I've been replacing them with compression fittings, which is what the cable company uses. They seem to cause much less hassle.

wow....the Cox tech came today...looke at the coax cables on the splitter (to TiVo and Internet router) and right away pointed out that it was poor quality and was interefering with the channel signal.

replaced with RG6 cable, and low and behold.....my channel signal strength is now 100.

Haven't noticed any pixelation yet. He warned me though that the pixelation happens regardless of signal strength...though TiVo boxes seem to be more prone to it than the Cox DVR.

Great news...thanks for sharing. As someone famous once said..."Pixelation do happen". A little here and there is to be expected. We see it once in a while OTA direct to our TV...no TiVo in the loop.

I suspect a lot of issues could be cleared up by replacing coax, Ethernet, HDMI and any other assorted cables. I know I have a bad habit of using whatever I have thinking that it's the best quality stuff and then remembering that it was the best I could get when I bought it...five years ago or whatever. Then a lot of us have no control over what the cableco's have installed outside so we're at their mercy to some extent.

I think the last part is a fair statement. Cableco's have dedicated equipment designed to operate within their parameters. TiVo's have to work across a wide variety of cable companies, equipment, quality of service, etc. With so many variables, it has to be a real nightmare to get everything to work properly sometimes.

I just recently started to get pixelation on one channel in particular(NBC HD). Ever other channel seems fine. I rebooted the Tivo and it seems to clear up for an hour or so. I am about to call Comcast, but have a feeling they will say it is the tivo. Any troubleshooting ideas I should try?

I'm having this exact issue as well. Where are you located?

I have one Comcast Multistream cable card. I seem to have excellent signal strength -- showing 100 / 36 SN ratio for NBC.

Every HD recording I've made from NBC in the last week is useless. On hour long programs, I get a partial recording, usually about 54-57 minutes in length. On a half hour recording, I get a partial recording about 26-28 minutes in length. The entire recording is unwatchable. I get about 1-2 seconds of viewable video, then pixelation, then another 1-2 seconds of video... I can't tell much with the audio because I don't get a consistent signal long enough for my receiver to lock on. I get a few words here and there but mostly nothing.

Tonight, I was recording something on both tuners. NBC on one, ABC & MSNBC on the other. The SD program from MSNBC looks fine. NBC & ABC HD programs are unwatchable. I wonder if the problem has something to do with recording on both tuners.

Comcast was, surprise, no help. They say everything is A-OK on their end. They said to call Tivo. One other issue, I've been having pretty severe intermittent issues with my Comcast internet service lately. But it's pretty sporadic, and doesn't seem to coincide time-wise in any way with my Tivo issues. I tried to get a Comcast tech out this morning, but he called me and asked, "Is your internet up right now?" I said yes, and he said he wouldn't come troubleshoot unless it was actually down. I guess I'll be lying about that next time.

I rebooted to see if this helps, but certainly the recordings themselves are incomplete. Maybe more frequent reboots will help for next time.

Has anyone called Tivo, maybe gotten a replacement unit, and been able to work around these issues?

Well, three days and still no pixilization. I am not sure if it was the RF Supressor fixed the problem, but I could not be happier.

Rich, I opened the home owner access panel at the box but did not see anything. I assume the supressor is inside the technitions panel. I will keep an eye on the TV and update this groop if I see any changes.

It would be interesting to see if anyone else in the Plano area could see if this fix wil work for them as well.

Thanks for that Scott. I thought it was something they installed inside your home.

Hello. If you have any suggestions, please help. I had major pixelation issues on the HD channels only with Comcast Cable Company for a while with the Series 3. When the upgrade happened to 9.2, I have very LIMITED pixelation on the HD channels (mainly ABC and NBC), but it was very tolerable. All of a sudden tonight, I noticed tons of pixelation. Does anyone have any suggestions? Does anyone know what is going on? I am located in Houston. Thanks!

I'm having similar problems. Pixelation was fine after 9.2 until this past Monday. Now I can barely watch an HD program. What's going on?? I'm in North New Jersey.

I just moved and I was hopeful that pixelation issues would go away because my signal was really bad in the old place. So...still had issues. Tried everything I could think of...the tech installed an amp, so I isolated the line for my TivoHD and tried it. Still had problems. Then, I had no problems....it just went away. Then, problems returned. Then, they came back.

I thought of everything...started brainstorming. Hmmm...maybe on the weekends, when more people in my neighborhood are watching tv, it affects my signal! No, that doesn't sound right. So I started trying to figure out, why would it come and go?

I've isolated it down to two possible solutions:

1. one of the cablecards sucks
2. one of the tuners is not working right

I came to this by tuning in to a known pixelating channel, (HBO) and watched. It pixelated. So I changed that channel to 002, then switched to the other tuner/card and changed to the known HBO pixelating channel. CLEAR. No problems at all, after leaving it there forever. Reversed the process, putting the other tuner/card onto HBO, and it was BACK. Pixelated again.

Did this over and over, and my conclusion HAS to be that one of the cards is not so good, or a tuner is not so good. My guess is that it is an SCARD problem with one of the cards. When I put the "bad" card onto a basic cable channel, it doesn't seem to have the problem either, so that makes me think it isn't decrypting so well.

Tomorrow I will take each card out one at a time to isolate which one is "bad" and see if my theory holds. If it does, then hopefully I will be able to get a tech to come out and give me a new card.

I guess my conclusion is to check and see if a pixelating channel does bad on both of your cards. If one is clear, the other might need to be changed out. Even if yours does bad on both cards, changing them out might help.

I'll update with more once I experiment by taking out the cards one at a time, and also when i get a tech out here to replace the suspected "bad" card.

Your problem sounds quite like the problem I had, which I reported in the TiVo HD Pixelation with 9.2a thread. The difference being that I had only a single M-card in my TiVo HD whereas you have two S-cards.

Quote:

My guess is that it is an SCARD problem with one of the cards.

My guess would be that you have a defective tuner in your TiVo HD.

When I had this problem, my best guess at the time was that if my single M-card was causing the pixelation, then I'd be seeing it on both tuners. I'm not sure that's a logical conclusion, but that was my best guess at the time. Apparently TiVo had a similar best guess too because they offered to replace my TiVo HD without even suggesting a cable card swap first. I haven't had pixelization problems since I got the new TiVo HD.

Unfortunately I couldn't get the lame RCN tech to try to pair up my existing M-card with my new TiVo HD. He insisted on putting in a new M-card instead, which left me unable to test my theory that it was the TiVo HD tuner causing the problem, not the cable card.

So we're both guessing and, unfortunately in many cases, so is TiVo support.

I'd be curious to know if your service number on your TiVo HD starts with 652-0001-803F-....? Just kind of wondering if there are bad tuners out there, are they bad in batches? Another wild guess of mine.

Hopefully you will have a different solution for this problem than I had. Shipping tivos back and forth was not so fun for me. I'm happy that I have a working TiVo HD now, but getting to that point wasn't the most positive experience of my life, to say the least.

My THD started to have bad pixelation yesterday and it was driving me crazy. I could not even watch any of my HD channels it was so bad. I went down to the basement and messed around with the wiring and splitters. I then went back to the TV and switched inputs to my HD Receiver (yes I kept it in case I ever wanted to use VOD). I was surprised to see it have the same pixelation issues my THD had. I wonder how many of these problems have nothing at all to do with the THD but only with the cable company. If I had not kept my HD Receiver I would have never known my THD was fine.

Hey, thanks for the responses. Fergie8, I think you win the bonus prize. (Wish I had one to give out ha ha).

Ok, today they sent a tech out and we went through four scards, pairing them patiently one at a time, first in slot 1, then in slot 2. This guy is getting some real TivoHD experience!! Hopefully someone else in my area can use it. Coincidentally, this is the same guy that came to my previous residence I mentioned. He originally came by that residence three weeks ago and when he left, literally said, "whew! glad I am done with this one!". Little did he know, he would get the same customer, same TivoHd,same German Shepherd at a new residence!! Ha! It was hilarious. At first he didn't recognize me, so I didn't let on.

Then he came into my new office (fourth room) and heard my dog in his crate going "police dog". The expression on his face, to be cliche, was priceless. He just goes, "OH NOOOOOO!"

Anyway, Fergie8 you were right. Every card we had worked fine on "tuner 0", RS Corrected and Uncorrected 0/0. Every card we had on "tuner 1" was both RS's going into the thousands.

So, my conclusion has to be that tuner 1 is messing up. Luckily, I bought the extended warranty from CC for $59.95 on the 29th day after my sale, the last day I could choose that option. I should be able to return this to CC and swap it out. (Now I am in the unfortunate position of having to start all over with updates, pairing cards, everything.)

But - I will know how to test from the moment I get the new one.

As a side note, I have Brighthouse here in Central Florida. The tech support on the phone, (even being kind), is not real good. When I was trying to repair the two cards myself, the techs kept balking and trying to tell me that I needed a tech to come out. When I say balking - I mean that they would go no further, to say they couldn't help me. I couldn't even tell them to just go over this on the phone.

This ended with one tech shutting off my service completely in my entire house (by accident?). My next call was to try and re-explain the whole situation, just to get the other tv's turned back on without waiting for the tech to arrive the next day!

Anyway, thanks for the responses. I will update when I get the new box and let you know if this solves my issues.

PS: The tech confirmed that the "preferred" signal strength is 0db coming in, but often techs will allow up to +10db because its tough to get an entire house at 0db in every outlet. I asked him if he had an RF supressor as some people using FSO said worked for them, but he said they don't carry them. They just split the signal. Messy I guess, but that's what they do. Since my problem seems to be tuner, not "hot" signal, I wasn't concerned, but thought I would mention it for those who think this is their problem. Good luck!!

I am getting pixelation on just a few channels. The channels are Disney, Food Network, and Discover. I am sure that it is on more, but these are the ones I watch a lot. It does not seem to happen on the HD channels, though.

It seems to have started about a month after I added an external eSATA drive, but not sure if it is connected. I tried to remove the eSata to test it, but was afraid I will lose all the programs as per the warning screen.

What can I do to check the system? Are there tests I can do? What suggestions do you guys have?

After some further investigating I did find that the feed through my HD receiver is less pixelated than the THD. I'm going today to buy some RG-6 quad shielded cable to replace what I have in the basement. I think it is a 100' run that is down there now and I can get by with 50', maybe even 25'. I also went ahead and ordered an Electroline 4-port amplified splitter off Ebay last night. I've read some good things about that splitter so hopefully I can boost the signal enough to get rid of the pixelation.

Do you know that you have a low signal level condition? Adding an amp to an already good signal level can make things worse. What does the TiVo indicate as signal strength and SNR on the channels that give you issues? Also what are are Corrected/Uncorrected counts?

My signal strenth goes from the mid 50's up to the low 70's on pretty much every HD channel I get. I have not paid much attention to the SNR, but I believe it's around 36-37. When I had my CableCards installed last week my signal was 100 and I had no pixelation whatsoever. I do not know what happened between then and now. I'm going to try a few things myself and if it still shows a low signal I'll call the cable company to come out and take a look.

Edit: I just bought me a 50' RG-6 Quad shield cable. I also ran by Radio Shack to get a 1' patch coax cable and decided to pick up one of their adjustable Bi-Directional Amplifiers. Might be trash but figured I'll hook it to the cable coming out of the wall and see what happens. Then when I get my Electroline I'll see which one works better. I think if I can boost my signal just a little I'll get much less pixelation.

Just an update: I switched out my TivoHD box today. That was good, no problem just walked in with the old, out with a brand new one. However, Brighthouse will not let me change the cable cards without calling out a tech....again. Even though I explained how easy it was, and I just needed to read them some numbers, the CSR said (after confirming with a supervisor and someone else) that they don't even have that field "editable" on their screen. The number the tech calls to do it is with someone else.

This sounds like one of those corporate decisions, where no one sees how much time and money could be saved by just letting the customer stick a card into a slot. But, I guess the vast majority of customers are using BH DVR's, not Tivos.

I will (hopefully) complete my update tomorrow after the tech comes back. (I really hope its the same guy I mentioned before!!)

Edit: I do have to stop and pause, thinking to myself, how many more TivoHD's could be sold if people didn't have to go through all of this?! Its not all on Tivo's shoulders, BH could make things easier, but most consumers just won't go through all this to get their box working.

Well as I figured the amplifier I bought from Radio Shack is junk. It did nothing to the signal. Even after running new RG-6U cable I still have a pixelation/tiling issue. I gave up and called Charter to have them send out a tech. I think something happened around the area that caused my signal to go way down. Hopefully they can figure it out today. I'll update later this evening after he leaves.

Hang in there. We had the same issue once and it turned out that the some of the lines they were using were "leaking the signal(?!)" during heavy rains (all of the power lines, cable, etc. are buried in the neighborhood). They had to send a "big truck" out to replace some of it and after that things were fine. Of course at first they said it was all good and no one had complained. Uh-huh.

I believe you are right. Everything has worked fine for the past 6 months, ablsolutely no pixelation. This past Saturday afternoon we had the most rain we've had in about a year. I recorded something that morning that was fine and something that night that had pixelation. I've already removed some splitters from downstairs so they cant try to blame signal loss on that. I'm trying to prepare myself for any other excuse they try to give me.
